TL;DR
This paper explores the role of particle-hole transformation in the Hubbard model, linking it to the AdS/CFT S-matrix, and constructs an achiral boundary with twisted Yangian symmetry for the open Hubbard chain.
Contribution
It reveals the significance of particle-hole transformation in connecting different S-matrices and introduces a novel achiral boundary with twisted Yangian symmetry.
Findings

Constructed an achiral boundary with twisted Yangian symmetry.
Highlights the role of supersymmetry in boundary conditions.
Abstract
We show that the particle-hole transformation in the Hubbard model has a crucial role in relating Shastry's R-matrix to the AdS/CFT S-matrix. In addition, we construct an achiral boundary for the open Hubbard chain which possesses twisted Yangian symmetry.
